Nice to see a game made with Allegro. Perhaps you could also make a Linux version for people like me who don't have Windows. Or better, consider releasing the sources of the game under an open source license if you're not planning to sell it.

Making a game is a huge accomplishment. I've never done it. For that I am envious.

I've spent a little time trying to build it for Linux, but have had little success. It would help if you specified which version of Lua and Allegro you used (it appears Allegro 4, so I don't think it matters which version, but it wouldn't hurt to know).
